<H2>scalegrid</H2>
<HR>
Set the ratio of magic internal units to lambda units
<HR>

<H3>Usage:</H3>
   <BLOCKQUOTE>
      <B>scalegrid</B> <I>a b</I> <BR><BR>
      <BLOCKQUOTE>
         where <I>a</I> and <I>b</I> are integers.
      </BLOCKQUOTE>
   </BLOCKQUOTE>

<H3>Summary:</H3>
   <BLOCKQUOTE>
      The <B>scalegrid</B> command sets the ratio of magic internal
      units to lambda units by rescaling the internal database and
      appropriate technology parameters.  The values <I>a</I> and
      <I>b</I> are interpreted to mean that all positions in the
      database should be multiplied by the factor <I>b</I> / <I>a</I>.
      An equivalent meaning is that there should be <I>b</I> internal
      units per <I>a</I> lambda units in the database.  For example,
      <BLOCKQUOTE>
	 <B>scalegrid 1 2</B>
      </BLOCKQUOTE>
      means 2 internal units per lambda, or an internal grid that is
      twice as finely spaced as the default.  The grid scaling can
      be queried using the <B>tech lambda</B> command.  Grid scaling
      is interpreted relative to the current scale, so
      <BLOCKQUOTE>
	 <B>scalegrid 1 2</B> <BR>
	 <B>scalegrid 1 2</B>
      </BLOCKQUOTE>
      results in 4 internal units per lambda. 
   </BLOCKQUOTE>

<H3>Implementation Notes:</H3>
   <BLOCKQUOTE>
      <B>scalegrid</B> is implemented as a built-in command in <B>magic</B>.
